Combo Chart

A Combo Chart is a versatile charting type that combines a clustered bar chart and line series, allowing you to display multiple data series in one chart area. This chart type allows you to specify a series type for each data grouping, giving you more control over how your data is displayed.
With a Combo Chart, you can easily compare data types, such as sales revenue and profit margin, in a single chart. The chart allows you to display each data series using the most appropriate chart type, such as a clustered bar chart or a line series.
The Combo Chart is a valuable tool for analyzing complex datasets and identifying patterns and trends in your data. With its ability to display multiple data series in one chart area, you can quickly and easily compare data and make informed decisions based on your findings.

Sample Table Format

MonthSales Revenue (Bar)Profit Margin (Line)Customer Acquisition (Bar)Employee Satisfaction (Line)

In this example, the Sales Revenue and Customer Acquisition data series are represented as bar charts, while the Profit Margin and Employee Satisfaction data series are displayed as line charts. This allows for easy comparison of the different data types, with each series represented using the most appropriate chart type.

Best practices for using combo charts

Combo charts are helpful when you want to display multiple data types on a single chart. Here are some best practices for using combo charts:
  • Choose the right chart types: Combo charts can include different charts, such as bar, line, and scatter. Choose the chart types that best represent the data you want to display. For example, if you show how sales revenue and profit margin change over time, a line chart might be best for revenue, while a bar chart might be best for profit margin.
  • Use consistent axes: When using multiple chart types on a single chart, it's important to ensure they are consistent across all the chart types. This means that the scales and units used on the axes should be the same. If the scales or units differ, it can be difficult for viewers to compare the data accurately.
  • Limit the number of chart types: While combo charts can help display multiple data types, it's important not to overload the chart with too many. Generally, limiting the chart to at least two or three chart types is best.
  • Use color and labeling effectively: To help viewers understand the chart, use color and labeling. Use different colors for each chart type to clarify which data points belong to which one. Label each chart type clearly, and include a legend to help viewers understand what each color represents.
  • Choose the proper chart layout: There are different ways to layout a combo chart, such as overlaying the chart types or using multiple axes. Choose the layout that best suits the data you want to display and makes it easy for viewers to understand the relationships between the data points.
